ALMON HUNT, OF MACOMB, ILLINOIS.

IMPROVEMENT-IN CULTIVATORS.

Specification forming part of Letters Patent No. 95,352, dated September 28, 1869.

, reference marked thereon.

Figure l of the drawings is a representation of a perspective view of my invention. Fig. 2 is a sectional view of the same. Figs. 3 and 4 are details.

My invention relates to cultivators; and it consists, mainly, in a novel arrangement of devices designed to serve as efficient means for the purpose named.

- The letters A of the drawings represent the wheels of a sulky-cultivator, and the lettersB two iirm bars that serve as the axle thereof. These bars are respectively turned upward at a point immediately adjoining the wheel-hubs, and are firmly riveted to the perpendicular parts of the frames C, next mentioned.

The letters C represent frames consisting of strong plates of metal or wood, bent or framed so as to form three sides of a square. They are respectively riveted to the vertical parts of the axles B at their sides and to the crossbeam D at their tops, in the manner shown.

The letter D represents a cross-beam riveted to and resting upon the upper horizontalparts of the frames C.

The letter F represents the neap, and letters G braces connecting the same and the crossbeam with the extreme inner ends of the lower horizontal parts of the frames C.

The letter II represents a pivoted bar resting upon the top of the neap, as shown, and letters K are equalizing draft-bars, bent and pivoted as shown, to work in conjunction with the bar Il in regulating and equalizing the draft upon the team.

It will be observed that between the two frames C th ere is aspace of considerable width, and that the cross-bar D is elevated above the same to a great height. This arrangement is made to provide for cultivating corn after it has grown too tall for cultivation by ordinary machines.

The letters a represent braces extending from the upright sides of frames C to the rear end of the neap.

The letters O represent my plow-beams with the plows attached. l

My method of attaching the plow-beam to the machine is as follows, namely: I make pin-holes in the lower horizontal parts of the frames C, adapted to receive and hold the pins d. I make also clampsy consisting of two plates of metal, with Ia plate of india-rubber between them, and fasten said plates firmly together in the manner shown on Fig. 3 ofthe drawings, leaving spaces in their front ends adapted to clasp over the bar of the frame C, as shown on Fig. l. The pins d, respectively, are passed through the jaw parts oi' these clamps, and

thereby a connection is formed withtheframes C. The clamps above described are marked P on the drawings.

To connect the clamps B with the plowbeams, respectively, I attach plates of metal to the sides of said beams and pass a pivot-pin through said plates and through said clamps at a point near the longitudinal center of said clamps.

By my peculiar method of attaching the clamps to the frames and the plow-beams double joints or hinges are formed, which permit the plows to be. moved up or down or sidewise at will.

I attach hooks s to the plow-beams, adapted for attachment to the braces c, for the purpose of suspending the plows from the ground,when desirable so to do, for transportation or otherwise.

The india-rubber plates betweeen the plates forming clamps P are marked c on the drawings.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

'Ihe cultivator herein described, having frames C, bars D, equalizing-bar B, clamps l?, and plates c, arranged with reference to the beams O, as described, constructed and arranged substantially as set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

ALMON HUNT. Witnesses:
